临盘油区所开发的三个油田,都是具有陆相沉积特点的复杂断块油田,本身天然能量不足,多属低饱和油藏,大多数断块边水不活跃,在天然能量开采下产能下降快,采收率低,本文论述了精细注水管理,提高复杂断块油藏注采完善程度,以保持地层能量,提高水驱油效率是实现我厂复杂断块油田长期稳产的根本途径。 The three oilfields developed in Linpan Oilfield are all complex fault block oilfields that have the characteristics of terrestrial sedimentation. Naturally, they are mostly low-saturated oil reservoirs, and most of the faulty waters are inactive. Under the exploitation of natural energy, This paper discusses the fine water injection management and improve the complexity of injection and production of complex fault block reservoirs in order to maintain formation energy and improve water flooding efficiency is the fundamental way to achieve long-term stable production of complex fault block oilfield in our plant .
